Retrieving the Component Type

As explained earlier, the first thing MapTag does is to retrieve the type of the component. It does this
by using the getComponentType operation:

public String getComponentType() {
return ("DemoMap");
}

The value returned from getComponentType must match
the value configured for the component with the component-type element
of the application’s application configuration resource file. Registering a Custom Component explains how to configure
a component.
